Application filed September 14, 1914.

T0 all whom it may concern lie it known that l, RICHARD MoR'roN, a citizen of the United States, residing at Casselton, in the county of Cass and State of North Dakota, have invented certain new and useful Improvements in llfrusses, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in adjustable trusses for use in connection with doors or the like, to prevent the same from warping, and to straighten those which are warped from exposure to the elements.

An object of this invention is the provision of a truss which consists of a plate adapted for connection to one face of a door or the like, the plate having an outwardly projecting threaded stem upon which a truss bar is loosely mounted, the opposite ends of the truss bar being adapted to engage against the side or end edges of the door, means being provided to force the truss bar inwardly toward the door to straighten the same.

A further object of this invention is the provision of a truss for application to doors or the like to straighten the same or to prevent them from warping, the device preventing the door from warping in the opposite direction after the same has been straightened, and the device being easily and quickly applied to new doors or to those which are already in use.

With these and other objects in view, my invention consists in the novel construction, combination, and arrangement of parts, to be hereinafter more fully described, claimed, and illustrated in the accompanying drawing, in which- Figure 1 is a longitudinal sectional view through a door or the like showing my improved device partly in section connected thereto; and Fig. 2 is an elevational view of my device showing the same connected to the door or the like.

Referring more particularly to the drawing, the numeral 1 designates a door or the like to which my improved truss is connected, the truss including a plate 2 which is secured centrally to the door by bolts or other suitable fastening devices, and projecting laterally from the plate is a threaded stem 3. The plate 2 is secured to the face of the door toward which the edges have warped, and loosely mounted on the stem 3 Specification of Letters Patent.

is a truss bar 11. The truss bar is provided with an enlarged medial portion 5 through which an opening G is formed to receive the stem therethrough, and the opposite ends of the bar extend inwardly and are provided at their extremities with heads 7 from which prongs 8 project laterally for engagement in the body of the door. The heads 7 are also provided with openings 9 therein to receive outwardly projecting bolts 10 which are mounted in the door, nuts 11 being mounted on the extremities of the bolts 10 to force the heads 7 against the face of the door, and the prongs 8 into the door. A nut 12 is preferably mounted on the stem 3 inwardly of the truss bar, and a similar nut 13 is mounted on the stem 3 outwardly of the truss bar, by means of which the truss bar may be moved inwardly upon the stem so that the opposite ends of the bar which engage the door at its warped edges are forced against the same to straighten the door.

In the practical use of my improved device, when the same is used to straighten a warped door, the plate 2 is secured to the face of the door toward which the edges thereof have warped, and the bolts 10 are passed through the door at the warped edges thereof. The nut 12 is then threaded on the stem to a sufficient distance so that the truss bar may be mounted on the stem with the heads 7 thereof engaged over the bolts 10, whereupon the nuts 11 are threaded upon the bolts to force the heads against the face of the door, and the prongs 8 on the heads into the door. With the truss in this position, the nut 13 is threaded upon the outer end of the stem 3 to engage against the enlarged portion 5 of the bar, and the nut 13 is turned so as to move inwardly upon the stem, forcing the truss bar inwardly thereof until the door is straightened'to accurately fit its frame when the door is closed. The nut 12 is then threaded outwardly upon the stem to tightly bear against the inner face of the truss bar to prevent the door from warping in a direction opposite to that from which it has been straightened, the nut 12 preventing inward movement of the truss bar upon the stem, and the heads 7 of the truss bar holding the edges of the door against warping in either direction by reason of the engagement of the nuts against the opposite faces of the truss bar.

While I have illustrated and described my improved device as used in connection with doors, it will be understood that the same may be used in connection with other objects to great advantage, the same being used in connection with floors of automobiles, wagons or the like, and also being desirable for use in connection with window shutters, and blinds.

F rom the above description taken in connection with the accompanying drawing, it will be seen that I have provided a truss which is extremely simple in construction,

f so that the same may be readily applied to new doors or doors which are already in use, the truss being extremely eiicent and durable in use.

Having thus fully described my invention, what I desire to claim and secure by Letters Patent is A truss for doors and the like comprising a plate fixed centrally to the door, a threaded stem formed integral with the plate and projecting outwardly therefrom, bolts projecting outwardly from the door on opposite sides of the stem, a truss bar having an opening in the central portion thereof and its ends projecting upon an incline therefrom, the ends of said truss rod being provided with perforated heads to receive the projecting bolts, nuts threaded upon the threaded ends of said bolts to retain said heads in position thereon, nuts threaded upon the stem and disposed upon opposite sides of the center of the bar, and inwardly projecting points formed at the extreme RICHARD MORTON.
